> CommandLine.toString() produces same output for different command lines. This may be
very confusing during troubleshooting and may lead to incorrect assumptions. For example,
if actual command to invoke was sh -c "echo 1" it might be displayed (in debug output for
example) as sh -c echo 1 (that will work incorrectly) and incorrect assumption might be made.
> Proposal is to make it clear what every parameter actually is. For example, following
code
>         CommandLine cmd1 = new CommandLine("sh").addArgument("-c").addArgument("echo
1", false);
>         CommandLine cmd2 = new CommandLine("sh").addArgument("-c").addArgument("echo").addArgument("1");
>         System.out.println("cmd1: " + cmd1.toString());
>         System.out.println("cmd2: " + cmd2.toString());
> will produce confusing output
> cmd1: sh -c echo 1
> cmd2: sh -c echo 1
> Same time, following output might be more helpful to figure out cause of some problem
or to prove that there are no problems with how parameters are set:
> cmd1: [sh, -c, echo 1]
> cmd2: [sh, -c, echo, 1]
